Abstract

Compared to measuring static range of motion (ROM) the assessment of dynamic ROM has received very little research attention. The purpose of this study therefore was to determine the reliability of the siliconCOACH motion analysis system for assessing dynamic ROM of the knee joint.Test–retest reliability.Laboratory.Ten male subjects unable to fully extend their knee at 90° of hip flexion.Static and dynamic ROM over four separate occasions using a video camera and siliconCOACH digitized footage.The variation between days for both static and dynamic measurements was minimal (CV
